  • Engineering Properties of a Pumice Sand Semantic Scholar

    Extensive deposits of pumice sand are found in various parts of the North Island of New Zealand, and their soft grained nature raises questions about their engineering properties. This stone describes an investigation of the basic properties of such a sand. The first part of the investigation involves laboratory measurements of compressibility and strength, and the second part looks

  • Pumice versus Perlite

    As for pumice, I've never seen it used for anything except for scraping your heels in the shower. It is a lot more dense than perlite. Both are mined from the earth, but pumice is produced naturally by volcanic activity, while perlite is mechanically heated until it explodes like popcorn. Hope this sheds some light on each.
